WINDWIILL.

SEEGIFICATION forming part of Letters Patent N0. 696,622, dated April 1, 1902.

Application filed June 17, 1901. Serial No. 64,884. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM BAUER, a citizen of the United States, residing at Loyal, in'

being thoroughly effective for operation lia bility of damage or breakage in use will be reduced to aminimum and in case of derangement repair may be readily effected.

WVith these and many other objects in view, which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts of awindmill-sailadjusting mechanism, hereinafter more fully described, illustrated, and claimed.

In the accompanying drawings, forming a part of this specification, and in which like numerals of reference indicate corresponding parts, I have illustrated a form of embodiment of my invention capable of carrying the same into effect, it being understood that the exact arrangement of parts,their proportions, and the manner in which they cooperate with relation to each other may be modified or changed without departing from the spirit of the invention, and in these drawings- Figure 1 is a view in perspective, exhibit-- ingawindmill-wheel embodyingmyimprovelnents. Fig. 2 is a View in front elevation. Fig. 3 is a view in side elevation, partly in section, showing more particularly the actuating means for the sails and also the manner of connection between the sails and said mechanism. Fig. 4 is a detached fragmentary detail view in perspective, on an enlarged scale, showingmore particularly the construction of the spokes, crank arms, and slotted band carried by the hub of the windmill-wheel with which the crank-arms coact. Fig. 5 is a fragmentary detail view showing a part of the supporting means for the wheelspokes.

Referring to the drawings, 1 designates a hollow tubular rotatable shaft, carrying at its outer end, or that facing the wind in operation, an enlarged cylindrical hub 2. As here shown, the hub and shaft are integral; but it is to be understood that these may be in separate parts and suitably assembled. The rear end of the shaft is chambered out, as at 3, to receive a coiled spring 4, one end of which bears against the wall 5 of the chamber 3 and the other end against a collar 6, carried by an endwise-shiftable trip-rod 7, journaled in the shaft, the outer end of the rod being provided with a hollow cap-shaped head 8, the connection between the head and the rod being in this instance through the medium of a pin 9, although the assemblage between these parts may be otherwise effected, if desired. The shaft 1 transmits mo-. tion to the pump-rod in the usual or any preferred manner, and as this forms nopart 0f the present invention illustration thereof is deemed unnecessary.

It will be understood that the hollow shaft and the trip-rod rotate simultaneously, and the shaft is held against endwise movement by means of a suitable bearing-support A, and said shaft is provided with opposite marginal shoulders or collars a, lying at opposite sides of the bearing, so as to prevent endwise movement of the shaft.

The wheel comprises a rim 10, carrying a plurality of sails 11, the sails to be of any preferred construction, the form herein shown being one that will be effective in operation.

' Thesails are secured to spokes 12, the outer ends of which are reduced to fit in openings 13 in the rim and to project beyond the same, as clearly shown in Figs. 1 and 2. The inner portions of the spokes are reduced to provide journals 14, these to work in bearings 15, formed, respectively, in the outer edge of the hub 2 and on the inner edge of a series of segments 16, constituting when assembled a clamping-ring 16, as clearly shown in Fig. 2. The arms from the journals 14 are bent at an angle to the length of the spokes to present one member 17 of a crank-arm, the other member 18 of which projects at right angles to the member 17 and extends into slotted openings 19, arranged in a band 20, secured to the outer edge of a rim portion 21 of the head, the inner face or edge of the band 20 to bear against the wall of the hub 2, and thus to hold the sails out of the wind. Each slot 19 in the band 20 comprises a member 22, disposed at right angles to the face of the band, and a member 23, extending parallel with the edge of the band, the walls of the lateral member presenting bearings against which the member 18 of the crank-arm bears, as clearly shown in Fig. 4. As herein shown, the band 20 is secured to the rim 21 through the medium of bolts or screws-24; butit is to be understood that, if preferred, the band 20 may form an integral part of the rim 21 and still be within the scope of the invention.

The object for making the clamping-ring 16 in sections or segments is to provide a ready means by which one or two of the sails may be removed in case of damage without interferingwith the rest, and, as here shown, each segment is of a length to hold two of the spokes assembled with the chamber; but it is to be understood that I do not limit myself to this precise arrangement, as the segments may be of a length to hold more than two of the spokes in place or only one.

Upon the shaft 1 is a flange 25, to which is secured one member 26 of a plurality of stayrods, the other member 27 of which is shown in this instance as held between the clamping-ring and the outer edge of the hub 2, the two members 26 and 27 being made of a single piece of metal bent to the appropriate shape and having its bend or apex secured to theinner side of the rim by bolts 28, as clearly shown in Figs. 1 and 3. This form of brace for the rim will be found thoroughly effective in use and owing to its simplicity of construction will generally be employed; but other forms of stays may be employed without departing from the scope of the invention.

The stress of the spring 4 operates normally and automatically to keep the sails out of gear, and to throw the sails into gear any preferred arrangement of mechanism may be employed, that shown herein being one of many ways of accomplishing the result. The shifting mechanism cooperatin g with the triprod 7 for throwing the sails into the Wind comprises an L-lever 29, the elbow of which is pivoted to a suitable support 30 by a bolt 30*, the upper or Vertical member of the lever being provided with a yoke 31 to straddle the rear projected end of the trip-rod, each yoke member having a slot 32 to be engaged by pins 33, carried by a block 33, loosely mounted on the trip-rod, the block being held against longitudinal movement thereon by collars 34:, bolted to the rod on each side of the block. To the lower member of the lever is connected a rope or chain 34 to pass to the ground and to engage with a cleat (not shown) in the usual manner for holding the wheel in gear, as will presently appear. When it is desired to throw the sails into the wind or in gear, the rope 34* is drawn down, thereby rocking the lever 29 and pro jecting the trip-rod 7 forward. This movement of the rod moves the head 8 outward and with it the band 20, the movement of the band by reason of the coaction between the slots 19 and the crank-arm member 18 imparting a lateral turn to the spokes 12, thus throwing the sails into gear. When itis desired to throw the sails out of gear, the rope 84 is loosened and the spring 4 will automatically retract the rod 7 and through the mechanism described turn the sails out of gear.

It will be seen from the foregoing that while the parts employed for accomplishing the results described are few in number and are of simple construction they will by their coaction and cooperation effect the operating of the sails in a thoroughly efficient and positive manner, and, further, by reason of the manner in which they are assembled should any of the operative parts become deranged or broken they may be readily replaced or repaired with but slight expenditure of labor.

The vane for the wheel has not been shown herein, as it forms no part of the present invention, it being understood that any form of vane may be employed and associated with the wheel in any preferred manner, and that any style of tower may be employed for supporting the windmill.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

hat I claim is 1. In a windmill,a wind-wheel having shiftable sails, crank-arms for the sails, a rotatable non-shiftable shaft for the wheel, an endwise-shiftable trip-rod, and a detachable head carried by the rod and provided with recesses for the reception of the respective crankarms, each recess having a transverse entrance-opening.
